Not all might be aware of the Godox V860 II F flash that is compatible now with many Fuji Mirrorless cameras. We highly recommend it as it is affordable and powerful - It has a built-in Receiver and is compatible with the Godox X1 wireless series triggers. What we particular like about it is the Li-ion battery - with Max 1.5second recycle time for Full Power pops and over 650 Full Power pops on one charge - So with half power there is virtually no recycle time. No more struggling with AA batteries.
